摘要： PROBLEM TO BE SOLVED: To provide a method for producing a fiber reinforced thermoplastic resin sheet having good expansion properties and an apparatus for the method. SOLUTION: A sheet is formed from a web containing reinforcing fibers and a thermoplastic resin as main components. The web is heated to melt the resin and then is compressed temporarily under a linear pressure close to a theoretical thickness of the sheet. After that, the web is cooled and solidified with the linear pressure lifted. In this way, since the break and rearrangement of the fibers are prevented during the compression, cooling, and solidification of the web, a fiber reinforced thermoplastic resin sheet having good expansion properties can be produced. The product can be applied to members for automobiles and ceiling base materials which require lightweight and rigidity.

摘要： PURPOSE:To produce an arom. liq. crystal polyester efficiently without loading a stirrer too much by reducing the particle size of an arom. hydroxycarboxylic acid to a specified value or lower, adding an aliph. acid anhydride to the acid, and mixing them with each other under stirring. CONSTITUTION:The mean particle size of an arom. hydroxycarboxylic acid is reduced to 150mum or lower in the process for producing an arom. liq. crystal polyester by using the acid as the main raw material, adding an aliph. acid anhydride (e.g. acetic anhydride) to the acid, and mixing them with each other under stirring. While the acid in the form of secondary particles with a mean particle size higher than 150mum can not be slurried and makes stirring impossible, using the acid of which secondary particles have been broken to a mean particle size of 150mum or lower slurries the raw material of an aliph. liq. crystal polyester, e.g. acetic anhydride, and enables stirring, enabling the above- mentioned production.
